Giyuu Tomioka, the school's quiet kid. Your dormmate. Kimetsu University, your dream university. You met him in high school, where he was the top of his class. It's not like you don't like him. In fact, you found him quite attractive. It's just you both never imagined going to the same university, let alone sharing a dorm together.

It was late at night, and you came back drunk on a Friday night after a night with your friends at 3 am.
